To all whom it may concern:

Beit known that I, WILLIAM PEIEssNITZ BONWIOK, a subject of the Queen of Great Britain and Ireland, residing at Blomtleld Road, Paddington, London, in the county of Middlesex, England, have invented Improvements in Bottle-Stoppers, (for which I have obtained the following patents: British Patents No. 10,497, dated July 20, 18,88, and No. [o 11,674, dated July 22, 18895Victorian Patent No. 6,867, dated July 5, 1889; Belgian Patents No. 86,543, dated June 6, 1889, and No. 90,967,

dated June 19, 1890, and German Patent No. 50,119, dated June 6, 1889,) ot' which the following is a specilication.

My invention relates to an improved bottle'- stopper, consisting of a combination in one of a valve, a button or knob, (hereinafter called a knob,) a connecting part, (hereinafter 2o called a stem,) a groove bounded by said valve, knob, and stem, and one or more channels or passages formed partly in the knob and partly in the stem, the arrangementbeing such when applied to a bottle suitably formed 2 5 with an internal groove and iitted with one or more elastic rings' surrounding the stern of the stopper and charged with aerated liquid that the pressure of gas in the bottle will keep the valve normally against an elastic seat formed by said ring, or by one of them when using more than one; but if the bottle be inverted and the knob be pressed the valve will be caused to leave its seat, liquid will flow out of the bottle by the before-mentioned g5 channels, and if the knob be released the p valve will be returned to its seat by the pressure thereon of the gas, thus closing the bottle until the knob is again depressed. This construction enables any desired portion of the contents of the bottle to be withdrawn at pleasure.

When the stopper is applied to a bottle containing fermented liquor, I so construct and arrange the stopper and ring or rings that the stopper will be normally held to its seat by the action of said ring or rings.

Vhen this modified construction of stopper and ring or rings is applied to a bottle containing still liquid, the stopper is constructed with two channels, and to open the bottle must be moved inward suiiiciently far to cause both channels to be uncoveredor opened so that the liquid may iow out by one and air enter by the other. The channels or passages may advantageously be formed at opposite sides of the stopper. y Stoppers as described may be formed in one piece of glass.

In the accompanying drawings, Figure 1 is a vertical section of the neck of a bottle t- 6o ted with a stopper according to this invention, the stopper being shown closed. Fig. 2 is a similar view to Fig. 1, but showing the bottle-neck inverted and the stopper moved inward to the open position by an opener 65 resting upon the rim of a tumbler, which, as as well as the opener, is indicated in dotted lines. Fig.' 3 is a plan of the stopper and ring removed from the bottle-neck. Fig. 4 is an elevation of the stopper alone. Figs. 5 and 6 7o are respectively. a vertical sec-tion and a plan of a modified form of stopper with elastic ring. Figs. 7 and 8 and Figs. 9 and 10 are similar views to Figs. 5 and 6, respectively, illustrating other modified forms of stopper 7"5 with elastic ring. Fig. 11 isavertical section illustrating a modified form of bottle-neck and stopper therefor, and Fig..12 is an elevation of the stopper alone. Fig. 1 3 is a similar view to Fig. 11, illustrating a further modification. 8o

Fig. 14 is a vertical section showing abottleneck provided with a stopper and two elastic rings.

The bottle-stopper shown in Figs.A 1 to 4, inclusive, can be made in one piece, ot' suit- 85 able material. Usually I make it of glass, and it comprises a valve 1, a knob 2, a stem 3, and two channels 4 4, each made partlyin said knob and partly in said stem. These channels are parallel to the axis of the stop- 9o per and extend right through the knob 2, so that fluid can be discharged in a direction parallel to the axis and without being deflected laterally, as is the case when the channels do not extend through the knob, but are closed at the outer end or are made to eX- tond laterally to the sides of the stopper.

5 is an elastic ring of suitable materialsuch as indiarubber-inserted Within an internal annular groove 6, formed in the botroo tlc-neck. This elastic ring, when the bottle is to contain aerated liquid, need only loosely tit the annular groove 7, formed between the valve 1 of the stopper and the knob 2, and need not fit tightly upon the stem Such a stopper, when applied to a bottle containing aerated liquid, will be forced upward by the pressure of the gas within the bottle, so that its valve 1 will normally bear against the elastic ring 5, which forms a seat, as shown in Fig. l, and will thus hermetically close the bottle. If the bottle be inverted and the stopper be pressed inward by any suitable opener-as, for example, by that shown in dotted lines at A in Fig. 2-the valve 1 will be caused to leave its seat, so that the channels et will be partly uncovered, as shown, and liquid will ow out through said channels into a glass or tumbler B below, and if the stopper be released the valve will he returned to its seat, thus again closingthe bottle until the stopper is again pressed inward.

By making the lower part l of the stopper of the conoidal form shown it can be readily passed through the elastic ring to place itin position.

The opener A (shown in Fig. 2) comprises three arms to rest upon a glass, and a central hollow boss to'enter the bottle-mouth and press the stopper from its seat.

In Figs. 5 and G the elastic ring 5 is made cfa thickness corresponding approximately to the width of the groove 7 in the stopper, and its internal diameter is such as to closely fit the connectingstem 3, which forms the bottom of the groove, as shown. By this construction the ring normally holds the stopper in the closed position and effectually closes the discharge channel or channels therein. The lower end of each channel in this case terminates in the groove 7 at a point 8 a short distance above the lower side of the groove, so that the channel is effectually closed by the ring when the. stopper is in its normal position. Such a stopper with elastic ring, while applicable to a bottle containing aerated liquid, is especially applicable to bottles for containing fermented or still liquids, because immediately an external force applied to open the stopper is removed the elastic ring will raise the stopper intoa position in which it will close the discharge-channels 4 and effectually seal the bottle. When such a stopper is applied to a bottle containing still liquid and the stopper is opened, liquid will flow out by one of the channels and air will enter the bottle by the other.

The stopper, (shown in Figs. l. and 2,) instead of being formed with two independent lateral channels 4, may be formed with one channel only; but I consider it better to use two, as they can then be made smaller than when one only is used, and liability of the rin gbein g forced upward from its seat through the one channel when used with bottles containing liquid charged at a high presssure is obviatcd. The two lateral channels can be merged into one that may extend through the knob and stern 3 from one side to the other, as shown at et* in Figs. '7 and S, or the knob may be formed with one central channel 4 that communicates at its lower end with two lateral channels 4b, that pass through the stems, as shown in Figs. 9 and 10. To prevent the stopper being forced into the body of the bottle during the charging thereof with liquid under very high pressure, the lower part 1 of the stopper can be made of wedge form, as shown in Fig. 12, and the neck of the bottle can be contracted, as shown at 9, Fig. 11, so that should the stopper be unduly pressed inward it will be arrested by the contracted part n9 of the neck and be prevented from being forced from the ring 5. For a like purpose the bottle can be made with an internal annular shoulder 10 surrounding the bottle-mouth, as shown in Fig. 13, and the knob 2 can be enlarged at its upper end, as shown, so that should there be any tendency to force the stopper too far into the bottle the enlarged part of the knob will come into contact with the shoulder and prevent any further inward motion of the stopper.

The operation of the Stoppers (shown in Figs. 7 to 13, inclusive) is similar to that hereinbefore described with reference to liigs. 1 to 4.

In Fig. 1t a second ring 11 is shown interposed between the shoulder l0 in the bottlemouth and the under side of the enlarged part of the knob 2 for the purpose of keeping the stopper raised, and thus insuring a tight joint between the valve 1 and its Seat or ring 5. With this construction the annular groove 6 is not essential, and the bottle can be formed only with an annular surface or shoulder corresponding to the top side ofthe groove 6. (Shown in Fig. 14C.) This arangement of stopper and rings, though suitable for bottles containing aerated liquid, is more particularly suitable for bottles containing fermented liquors and still liquids.

In filling bottles fitted with Stoppers such as hereinbefore described with liquids under pressure, the illing-machine should be provided with a nozzle adapted to press the stopper inward and hold it in its open position during the filling operation, so that the bottle can be properly snift.

)Nhat I claim isHh 1. A bottle-stopper comprising a lower part forming a valve 1, a knob 2, a connecting-stem 3, a groove 7, formed by and between said knob, valve, and stem, and one or more exitchannels formed partly in said knob and partly in said stem and the lower end of each of which terminates in the said groove at a point below the top side of said groove and a short distance above the bottom side thereof, substantially as herein described, for the pur pose specied.

2. The combination, for stoppering a bottle, of a stopper formed with an external annular IOO IIO

groove and with an exit-channel, and an elassaid stopper and partly within an internal groove formed in the bottle-neck, said ring serving to carry said stopper and to normally close said exit-channel, substantially as herein described, for the purpose set forth.
